>
> When an exception is thrown in a server process, the Hadoop Server class
> passes the exception class name and error message across the wire to the
> Hadoop Client. The Hadoop Client then throws a RemoteException with the class
> name and error message as part of its payload. Thus an interface like:
> public HRegionInfo getRegionInfo(final Text regionName) throws
> NotServingRegionException;
> actually throws a RemoteException on the client with
> org.apache.hadoop.hbase.NotServingRegionException as the class name and the
> remote message as the message.
> Anywhere in the HBase code where we try to catch NotServingRegionException
> will thus never see it if it came across an RPC.
